flash to indicate this. In this situation, you must press the green key (“Enter”) to initiate
biometric identification.
It will automatically return to normal when the beam of light is no longer obstructed or
the external interference is removed (event
, code 0x0D).
In order to activate this detection method, it is necessary to configure the following
parameters:
•
CFG_Opt_T_Watchdog
): it allows activation of the LED optical
barrier. So:
- LED operation:
$80
(LED optical barrier on, obstruction timeout to 12.8 sec.).
If a second FIM module is connected, a special cable assembly allows using a Digital
Input to detect finger presence.
5.3.2. FIM Module
BioMax2
and
KBio2-Online
also allow finger presence detection by means of the
capacitive sensor embedded both in the OPP06 optical sensor and the capacitive sensors
that can be attached to the FIM5360 module (and later).
If two FIM devices are connected to a single
BioMax2
or
KBio2-Online
, the same
detection mechanism can be used.
In order to activate this detection method, the following parameters must be correctly
configured:
•
(
CFG_Opt_T_Watchdog
): it allows to select the finger detection
method, or disable it altogether.
- Required value:
$FF
(Auto-On enabled).
•
CFG_Serial_Port_Reader
): it is necessary to configure UART1 for
a FIM module, at the correct baud rate.
- Possible values:
$88
to
$8B
.
- Recommended value:
$8A
.
•
(
CFG_Main_Reader
): the FIM module must be declared here.
- Required value:
$05
(FIM module on UART1 for the main reader).
Optionally, a second FIM module with Auto-On detection may be connected. In this
event, UART0 will be used:
•
(
CFG_Serial_Port_Host
):it is necessary to configure UART0 for a
FIM module, at the correct baud rate.
- Possible values:
$88
to
$8B
.
- Recommended value:
$8A
.
•
(
CFG_Aux_Reader
): the second FIM module must be declared here.
- Required value:
$04
(FIM module on UART0 for the auxiliary reader).
